Perkins and Abshire escorted the girls to their dance. “We want you to forever know we are here with you always. It’s an absolute honor for us to get to take your girls to the dance,” Perkins told them.

“I keep thanking them,” said their mother, Anna Montgomery, “but they just keep saying, ‘It’s our honor.'”
